DAVID MYERS, OF COLUMBIA CITY, INDIANA.

VEHICLE-AXLE OILER.

SPECIFICATION forming part of Letters Patent No. 639,085, dated December 12, 1899.

Application filed June 30, 1899. Serial No. 722,375. (No model.)

To all whom it may concern:

Be it known that I, DAVID MYERS, a citizen of the United States, residing at Columbia City, in the county of Whitley, in the State of Indiana,have invented certain new and useful Improvements in Vehicle-Axle Oilers; and I do hereby declare that the following is a full,

clear, and exact description of the invention,

i which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to improvements in vehicle-axle oilers.

The object of my invention is to provide a cheap,simple, convenient, and efficient means for lubricating vehicle-axles Without the necessity of removing the nut upon the outer end of the spindle, which secures the wheel in position.

My improved means for convenient lubrication of vehicle-axles consists in providing the axle-spindle with a longitudinal oil-feed passage communicating, by means of a series of radial outlet ports or passages, with a peripheral oil-groove, in to which the oil is forced from the said feed-passage, and a removable plunger adapted to force the oil out of said feed-passage through the said outlet-ports into the said peripheraloil-groove, from which it is distributed in the usual manner to the entire surface of the spindle.

The novel feature of my invention resides in the construction whereby the lubrication of the spindle can be accomplished in a ready, convenient, and efficient manner without removing the vehicle-wheel.

Similar reference numerals indicate like parts throughout the several views,in which-- Figure 1 is a side view of my improvement, partly in longitudinal central section, show ing the longitudinal feed-passage, the peripheral groove, the connecting-ports, and the removable plunger which fits the said feed-passage. Fig. 2 is a similar View with the plunger removed. Fig. 3 is a detail of the plunger by which the oil is forced out of the feed-passage into the peripheral groove.

The axle 1, of any proper form and dimensions, is provided with an ordinary spindle 2, having the usual reduced screw-threaded termination 3 upon its outer end to receive the wheel-securing not 4, of common form, ex-' cepting that said not has a central screwthreaded opening, hereinafter described. A metallic sleeve 5 of common form is fixed to the interior of the hub, as usual, has its outer end adapted to be loosely received and inclosed by an annular flange on the inner face of said nut, and is provided at its enlarged inner end with a washer 6. j

The spindle 2 is provided With a peripheral oil-groove 7 of proper dimensions, extending from the rear end of the spindle to near the front end thereof. The spindle 2 also has a longitudinal opening 8, extending from the outer end of the spindle to a point preferably opposite the inner end of the said groove 7. This feed-opening 8 is connected with the said groove by a series of radial openings 9, the inner one of which is located at or near the inner end of the said feed-opening. A cylindrical plunger 10 is adapted to snugly fit the said opening and is provided with a milled head 11 and an enlarged screw-threaded portion 12 adjacent to the said milled head, which is adapted to fit the enlarged screwthreaded end of said opening 8.

The operation of inyimprovement is, briefly stated, as follows: When the oiling of the spindle 2 is desired, the operator unscrews and removes the plunger 10 by means of the head 11. He then inserts into said opening by a proper pneumatic pump or any other suitable means a proper quantity of oil, which can be so regulated as to be a predetermined measured quantity. The plunger 10 is then inserted into said opening 8, thereby forcing said oil upward into the said peripheral oilgroove 7 through the said ports 9. The said plunger is then firmly secured in position by screwing the said portion 12 thereof into its seat. All necessity for removing the :nut 4 or the wheel in oiling the vehicle-spindle is thus avoided.

Myimprovement is thus cheap, simple, con venient, and efficient and obviates the necessity for removing the vehicle-wheel in oiling its spindle.

Obviously the exact point upon the spindle 2 at which the peripheral oil-groove is located, whether upon its upper or lower face, is immaterial. So, also, the dimensions of said groove and the number and arrangement of the said ports 9 are immaterial.

What I desire to secure by Letters Patent The combination of a vehicle-spindle having a longitudinal oil-feed opening, a peripheral oil-groove arranged as shown, and a series of oil-passages connecting the said feed-opening' with the said peripheral groove; a hubsleeve loosely mounted on said spindle; a nut having a screw-threaded recess adapted to receive the outer screw-threaded end of said
